To make the night even more special for Suarez Navarro, who was playing her first night match inside of Arthur Ashe Stadium, the Spaniard was celebrating her 30th birthday.

“Maria has played here at night many times so I knew I needed to be aggressive, focussed and play solid,” Suarez Navarro said after the match. “I told myself to run and fight — that’s the way I can play really good tennis.”

Suarez Navarro, after taking the first set 6-4, dropped down 2-1 early in the second set. But, thanks to an insane rally, she quickly tied the set back up.

The loss marks the first time that Sharapova — the former World No. 1 who won the U.S. Open in 2006 — has failed to reach the quarterfinal round since 2012. It was, largely, her own errors that did her in. Sharapova posted 38 unforced errors on Monday night, compared to just 20 from Suarez Navarro.

Suarez Navarro will advance to the quarterfinals at the U.S. Open where she will take on No. 14 MadisonKeys, who beat No. 29 Dominika Cibulkova 6-1, 6-3 on Monday.

“Madison is from the United States so I guess all the crowd will be for her,” Suarez Navarro said after the match. “I have played her a few times. She has a great serve and plenty of experience on this court.”
